Firestop sealing
Sealing of openings and joints in fire-rated walls and floors to restore their resistance rating.
- Single and grouped penetrations
- Masonry, concrete and lightweight partitions
- Remediation of existing breaches
Firestop sealing, penetration protection and fire-rated joints. Compartments that meet the standards, executed with care on your sites across Belgium.
ZAYOUN specialises in passive fire protection. We seal openings through fire-rated walls and floors to stop the spread of fire, smoke and gases from one compartment to the next.
Every cable, pipe or duct penetration creates a breach in the fire resistance of a wall. Our job is to restore that resistance with the right system, installed by the book, and documented for building handover.
We work alongside main contractors, installers and engineering offices, from structural works to finishing.
The right system selected for each substrate and each type of penetration.
Installation that is neat, durable and easy to inspect on site.
Tested and classified systems that meet Belgian and European requirements.
Deadlines met and documentation handed over on delivery.
